Cairns water supply reaches critical level as more rain continues to worsen north Queensland floods

Cairns residents are being asked to only use water for emergency purposes, while communities further north cry out for immediate help, as the severe flooding emergency that has affected far north Queensland continued to unfold on Monday.

Numerous towns, from Cooktown to Innisfail, have become isolated by flood waters, with all major state roads and rail in the region cut.

Hundreds of residents have required evacuation, and Cairns airport remains closed after more than two metres of rain fell in less than a week in some towns, with more forecast on Monday.

Authorities said they were planning to evacuate the entire Indigenous community of Wujal Wujal, while nine people remained stranded on rooftops in the nearby communities of Bloomfield and Degarra.

The water supply in Cairns’ reservoirs has reached a critical level, with water treatment plants offline due to flooding.

“Emergency use is drinking only. Try not to, unfortunately, flush your toilets … grab some rain from outside to flush the toilet if need be,” Cairns mayor Terry James said.

More than 1,000 residents sought assistance from the State Emergency Service, while Fire and Rescue swift-water rescuers have responded to more than 370 callouts during that time.

On Sunday night, 300 people were rescued in what was an “extraordinarily challenging evening”, police commissioner Katarina Carroll said. The rescues were done with the help of the SES, police, civilian assistance, QFES and naval support, mostly in the areas of Machans Beach, Yorkeys Knob and Holloways Beach. More than 300 triple-zero calls were made to police.

The ADF will airlift extra QFES and police personnel to Cairns to assist.

Crocodiles have been spotted in floodwaters, from Ingham to Wujal Wujal, where nine people, including a young boy, were earlier stranded on the roof of the local health clinic, before later being able to self-evacuate.

There were 15,000 still without power on Monday morning.

Cairns airport will remain closed for all of Monday, after being forced to shut on Sunday due to record water levels inundating the aerodrome.

The Daintree River exceeded previous 120-year-old flood records by more than two metres on Monday.

Queensland premier Steven Miles told north Queensland residents on Monday that the government was doing all it could, amid ongoing difficult conditions.

“We know you’ve had a tough night… We have heroes on the ground who have been out all night. We deployed literally every boat we could get our hands on in Cairns to evacuate those who couldn’t safely evacuate themselves. And more help is on the way,” he said.

But Douglas shire council mayor Michael Kerr said the community around Mossman was “desperate” for immediate military aid, with many residents lacking power and water and in need of urgent evacuation.

“We do not have resources to deal with it,” he said.

“We have got… chemo patients, we have got newborn babies without nappies and food, we cannot get to them.

“We are desperate for military intervention to sort this situation out. And at this stage, we’re not getting any bite on it. We’ve had communities with no water for nearly 24 hours. We’ve got other areas who have no power or communications now for four or five days.”

Kerr said “we need to get resupply and evacuation happening”.

Kerr said they had received no warning of Sunday’s floods from the Bureau of Meteorology.

He had no estimate of the number of people cut off in parts of the shire, because council workers can’t get to them.

“This is just a mess. The military should have been all the way through here yesterday. We need help now,” he said.

The Bureau of Meteorology on Monday morning issued another severe weather warning for heavy and locally intense rainfall in the areas north of Cairns, which have already seen record-breaking flooding.

Areas from Hope Vale to Port Douglas have been warned there is potential for six-hourly totals of up to 300mm.

Further south, rain had cleared in Cairns although more showers were expected throughout the day.

Some towns have recorded more than 2m of rain in the past week, which is more than average annual rainfall total in Cairns.
